Our selection of 400 GPD RO Membranes

We supply the leading brands in reverse osmosis filtration. Vontron’s 400 GPD membranes are known for high-accuracy water filtration, removing anything from dissolved solids to waste and harmful compounds in the water.

By using pressure to push water through pores as small as 0.0001 microns, these filters block out any impurity, including heavy metals. They can last six months to a year, ensuring you have purified water for your fish for a long time.

We also stock membrane housings that are crafted from durable materials and can be used for 200 and 300 GPD membranes as well. They are made to handle heavy usage and large amounts of water.
